Answer:
7m-7m=8n+8n
m=16n
Step-by-step explanation: U must first link the like terms so in order to do so u must bring over the 7m, now before u brought over the 7m it was a positive 7m now that your bring it over it turns negeitive and the same goes for the term 8n when u carry that term over it turns positive now dont let the subtraction sign foul u it still negative as long as its beside the term it is going to be negative guys dont forget that, now on to the next step after u cross over and change signs u start to work out now that the like terms are equal u dont need to worry about them because its given u the go ahead to workout so your main focus is on the subtracting the 7's which is 0 and leaves u with m u dont have to put them but i dont recommend it the u start on the next side u and the 8's which is 16 and u put bk the n u have to put bk the terms its important and thats how u get m=16n.
The mathematical expression that Katherine requires to know the price of the objects that she is going to buy is 8 * ($20.75) + 120 * ($5/12) = $216
<h3>How to write an expression for this procedure?</h3>
To find a mathematical expression for this procedure we must take into account the values that we know.
For example, we know that it requires 15 pansies for each tree. This can be expressed like this:
On the other hand, we must calculate the price of each tree and the pansies that are going to be used to surround each one as shown below.
- Cost of trees = 8 * $20.75
- Pansies Cost = 15 * ($5/12)
According to the above, the final expression, in which all the necessary data for Katherine is included, is:
- 8 * ($20.75) + 120 * ($5/12) = $216
